For the reaction N2 + 3H2 -> 2NH3, the rate of disappearance of H2 is how many times the rate of disappearance of N2?

Answer: 3 times.

A 3 times
B 1 time (equal)
C 2 times
D One-third

Correct answer: A. 3 times

Explanation: By stoichiometry, 3 moles of H2 are consumed per mole of N2, so H2 disappears 3 times as fast as N2.

First-order decay curve: concentration halves every t½, and that half-life is constant - a defining test for first-order kinetics.

Concept context

Study the speed of reactions and what affects it: concentration, temperature, and catalysts. Covers rate law, order of reaction, the Arrhenius equation, and reaction mechanisms step by step.
